## What you would see

A vertical page of creamy parchment, slightly aged at the edges, holds at the top a small painted scene framed as if by a stone doorway, and below it a block of Latin text. The frame is sandy gold, with two columns decorated with carved-looking spirals and small knots, a lintel above, and a step below. On the lintel a small cartouche reads 'Suffragia', and beneath it, in red letters, 'De sancto petro. Antiphona.' Inside, Saint Peter stands full-length on a strip of dark green grass. He is an older man, bald with white hair at the sides and a short white beard, with a thin pale halo around his head. He wears a long blue robe patterned with gold motifs and a broad reddish-brown mantle draped over his shoulders, fastened with a round gold brooch. In his right hand he holds an open book with fine lines of writing; behind his left shoulder rises a large silver key. His gaze turns slightly to one side and his expression is calm. Behind him runs a low gray stone wall; beyond it, on the left, green and yellow hills, and on the right, a blue sea under a bright sky. Below, the printed text in black Gothic letter has red initials and highlighted words, plus a large blue initial with gold decoration at the start of the prayer.

## How to look at it

First look at the large key rising behind Saint Peter's shoulder, the attribute that identifies him. Then move down to the open book in his hands and to the Latin prayer below, which is part of the image's function. Finally, notice the painted frame: it imitates architecture, but its columns end up framing printed text just as much as the saint.

## Context

This page comes from a printed Book of Hours for the Use of Rome, made in Paris in 1510 by Guillaume Le Rouge (active 1493–1517). According to the Cleveland Museum of Art, the volume has 112 folios printed on parchment and bound. Books of Hours were personal prayer books, widely owned in late medieval Europe, with prayers organized by times of day and by devotions to the Virgin and the saints. Folio 99r belongs to the Suffrages, prayers asking for a saint's intercession; here the saint is Peter. The visible Latin text includes the words 'Tu es Petrus' ('You are Peter'), linked to the tradition of Peter as keeper of the keys of heaven.

## Curious detail

Although the text and outline were printed, the color was applied by hand, so copies of this same edition could look subtly different from one another.

## Questions

- What changes when a devotional book is printed but still painted by hand and made on parchment?
- Why pair an image of Saint Peter with a key, a book, and a prayer on the same page?
- How does the architectural frame affect the way we read the text below the image?
